Now that we have our results, it is important that we check to see that our computational simulation is accurate. One possible way of accomplishing this task is comparing to the pre-calculations, as we did in the results section. Another way to check our results is by refining the mesh further. The smaller the elements in the mesh, the more accurate our simulation will be, but the simulation will take longer. To refine the mesh, look to the outline tree and click Mesh > Face Sizing Change the element sizing to 0.25 025 in (half the size of the mesh we originally tried). The new mesh looks like this . It has twice as many elements as the original.

Maximum Sigma_xx | Maximum Deformation | |
|---|---|---|
Theory Values | 3.0033 x 10^6 psi | 1 0.1724 |
Original Mesh | 3.0336 x 10^6 psi | 1 0.1761 |
Refined Mesh | 3.0360 x 10^6 psi | 1 0.1700 |
As one can see from the table above the results do not change greatly as the mesh is refined. This means we don't need to refine the mesh further.
